SHUTTLE FOR LOOMS.

SPECIFICATION forming partpf Letters Patent No. 675,810,1dated June 4,1901.

Application filed September 7, 1900. Serial No. 29,287. (No model.)

T0 all whom ir' may con/cern:

Be it known that I, JOHN C. BRYAN, a citizen of the United States,residing at Augusta, in the county of Richmond and State of Georgia,have invented a new and useful Shuttle for Looms, of which the followingis a specification.

This invention relates to shuttles for looms, and more particularly tomeans for facilitating the automatic threading and feeding the threadfrom the bobbin, the objects in View being to effect these operations ina positive manner without obstructing the movement of the shuttle underinstrumentalities ordinarily employed in a loom organization and tosimplify the construction without affecting the strength of theshuttle-body or materially increasing its cost of manufacture.

The invention primarily consists in a shuttle having a thread-apertureextending diagonally through a portion of one end of the body thereofand in communication with a throat that opens out exteriorly and guardedby an overhanging lip, an eye of a specific form being located adjacentthe delivery extremity of the said aperture and having means fordirecting the thread thereinto and holding it against accidentaldisengagement.

The invention secondarily consists in the details of construction andarrangement of the several parts of the eye, which will be more fullyhereinafter described and claimed.

In the drawings, Figure l is a perspective view of a shuttle embodyingthe features of the invention. Fig. 2 is a side elevation of the same.Fig. 3 is a horizontal section on the line 3 3, Fig. 2. Fig. 4. is a topplan view of the eye-blank. Fig. 5 is a longitudinal vertical section ofthe eye-blank, showing a portion thereof bent over in dotted lines. Fig.6 is a detail perspective view of the completed blank.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral l designates a shuttle-body which, as usual, is preferablyconstructed of Wood and has the opposite extremities 2 and 3 similarlytapered and each provided with a metallic nose 4, comprising a shank 5,as shown by Fig. 3, fastened by a pin 6 to prevent it from working looseand also to strengthen the shuttle. A carrier or bobbin slot 7 is cutthrough the body l in a horizontal plane completely from one side to theother.

In the tapered extremity 3 a thread-aperture 8 is formed in a diagonalplane and extends from about the center of the front end wall of theslot 7 outwardly through one side of said extremity near the nose 4. Theopposite terminals of the said aperture are increased in dimensions, asat 9 and l0, to permit the thread to have free play on entering andexiting into and from the same, and thus materially avoid Wear and alsoinjury to the thread. Near the bottom side of the extremity 3 in whichthe thread-aperture 8 is formed an elongated throat ll communicates withsaid aperture and opens outwardly at said side, the said throatextending completely from the front end Wall of the slot 8 to thedelivery terminal or enlargement 9 of the aperture and is guarded by anoverhanging lip l2, which has the lower corner 13 thereof adjacent thefront end wall of the slot 8 regularly curved or rounded to facilitatethe ingress of the thread into the aperture 8 through the throat andwithout catching upon obstructing corners or angles. The throat l1 hasan upward inclination, and when the bobbin is in position in the shuttlethe free end of the spindle thereof is directly in line with the innerenlarged extremity 10 of the said thread-aperture, and a resistance willthus be offered against the easy disconnection of the thread from thethread-aperture after the shuttle has been properly threaded. It will beobserved that the entrance to the throat ll is disposed at a low level,and this is for the purpose of insuring the entrance of the thread intothe aperture 8 when the shuttle is automatically filled by the fillingmechanism with which it is adapted to be used. This filling mechanismmay be of any form, as the construction of the shuttle is notnecessarily dependent upon any precise arrangement of parts in thefilling mechanism.

As an effective auxiliary in making the self-threading operation of theshuttle positive and practical an eye 14 is fitted in and heldrelatively to the thread-aperture 8. This IOO eye is pushed inward intothe outer enlarged delivery-terminal of the said aperture 8 and is ofthe form and construction clearly shown by Figs. 4, 5, and (5, andcomprises a hook member 15 and a body 16, primarily constructed in theform of a blank, as shown by Fig. 4. The body 16 is formed with anelongated concaved depression 17 in alinement with the hook member 15,and between said hook member andthe depression a convex guard 18 isformed in said body by striking the same upwardly from the lower side.The hook member 15 also has its free extremity formed with a concavedepression 10, which provides a guard projection 2O on the opposite sidefor a purpose which will be hereinafter set forth.

In producing the eye from the blank set forth the hook member 15 isturned or doubled over the body or support 16 and bent in spiral contourin a regular curve and the terminal of said hook member is brought closeto the convex guard 18, which will now stand opposite the same in thebend made in forming the said hook. The guard projection 2O will be nowlocated in the depression 17, just suilicient space being left betweenthe greatest extent of the said guard projection and the depression, aswell as between the terminal of the hook and the guard 1S, to permit thethread to pass between the same into the hook; but the thread will beprevented from accidentally becoming disengaged from the hook by theguard 1S, which will throw it over against the internal portion of thebody of the hook and past the small opening where it entered. Thisarrangement of the eye is clearly shown on an enlarged scale in Fig. G,and it is intended that the hook and body be given a slight convergingcontour to aline with the aperture S and snugly fit the innertermination of the enlargement t). \Vhcn the eye is fully positioned inthe enlargement itislirmlysecured byasingle fastening-screw 2l, passedtherethrough into the adjacent material of the shuttle. The head ot' thesaid screw is in a position, however, to accommodate an easy applicationor removal of the eye, and while this eye is particularly intended foruse in the form of shuttle shown it will be understood that it iscontemplated to make its use general, and particularly in all forms otself-threading shuttles to which it maybe applicable.

The entrance of the thread from the bobbin or carrier into the throatleading to the aperture S is facilitated by the movement of the threaditself by unwiuding from the end of the carrier or bobbin-spindle andthe tension exerted on the thread during the time it is held by a partot the filling mechanism, and in the threading operation the side of theex tremit-y through which the said throat opens outwardly will beadjacent the said filling mechanism. The improved eye can also be usedin hand-threaded shuttles.

Having thus described the invention,what is claimed as new is- 1. In ashuttle for looms, the combination of a body having a slot for thereception of a carrier or bobbin, and a thread-aperture in one extremitywith an outwardly-opening downwardly-inclined throat communicatingtherewith, and an eye in the delivery extremity of said throat.

2. In a shuttle for looms, a body having means for receiving and holdinga carrier or bobbin and a thread-aperture through one extremity providedwith an outwardly-opening throat having a downward inclination and anoverhanging lip.

3. In a shuttle for looms, a body having means for receiving and holdinga carrier or bobbin, and a thread-aperture through one extremityprovided with an outwardly-opening throat with a downward inclinationand a low external entrance guarded by an overhanging lip.

4. A shuttle for looms, having a threadaperture with an externalentrance-opening throat having an upward angle of inclination to thethroat and guarded by an outer overhanging lip.

5. A shuttle for looms, comprising a body having anoutwardly-openingthread-aperture through one extremity with oppositeterminal enlargements, the said aperture being down ward ly inclined andguarded by an overhanging lip having an inner rounded corner.

G. An eye t'or the th read-apertu re of a loomshuttle consisting of ahook provided with an inturned terminal and a guard in the body adjacentsaid terminal adapted to deflect the thread past the opening between thehookterminal and said guard.

7. An eye for the thread-aperture of a loomshuttle, comprising aninturned hook and a guard opposite the terminal of said hook struck outfrom the body ofthe latter.

S. An eye for the thread-aperture ot' a loomshuttle comprising aninturned hook and a convex guard adjacent to and struck out from thefree terminal portion of said hook.

t). An eye for the thread-aperture of a loomshuttle consisting of a bodyhaving an inturned hook provided with a guard projection located overand partially in a depression in said body, the latter also having aguard adjacent to the terminal of the hook.

lO. A n eye for the thread-aperture ot` a loomshuttle having an inturnedhook with an outstruck projecting guard near the free terminal thereof,the body of the eye also having an ontstruck guard near thehook-terminal in a reverse plane to that of the latter.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in the presence ol' two witnesses.

JOHN C. BRYAN.
